Specification of Letters Patent.

Patented nec. 24, 1907.

` Application met May 19.1906. serial No. 317.761.

To all whom 'it may concern: v Be it known that I, JOSEPH L. CAUSEY,

citizen ofthe United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements 'in Oil-Burners, of which the following is a specification.

This invention relates to oil burners and While designed more especially for use in' bake ovens and furnaces may of course be used wherever adaptable, and my object to produce an oil burner which operate efficiently and reliably, which can be regulated in its heat'` developing capacity and with which combustion takes place with com aratively little sound. viith this objectA in view and others' as hereinafter explained, the invention consists in certain novel andpeculiar features of construction andyorganization as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying'drawing, in Which.-

Figure 1, is a horizontal section of a burner embodying my invention, taken on the line I-I of Fig. 3. Fig. 2, is a side view of a portion of the burner. Fig. 3 is a.crosssection taken on the line III-III of Fig. 1. Fig. 4, is a cross section on the line IV-IV of Fig. 1. Fig. 5, is a side view of the extremity of the burner-tube extension. Fig. 6, is a section on the line VI-VI of Fig. 7, showing a modified construction of the front end of the Fig. 7, is a horizontal section on the line VII-VII of Fig. 6.

In the description and claims the Word fluid is intended to cover air or steam as distinguished from oil, as either of the firstnamed fluids may be employed with satisfactory results.

In the said drawings, 1 indicates the' body portion of the burner, the same being of cyindrical form and externally threaded forwardand rearward of the laterally projecting internally threaded bosses 2 and 3. The

. bustible material.

Vtherear end of fluid passage 10 formed around but separated from the contiguous portion of the oil passage 7, an oil pipe 1 1 being screwed into boss 3 to supply oil to passage 7 through the srall connecting passage 12.

The valve for controlling the passage of oil to the burner, com rises a threaded portion 13`engaging threa s 8, a portion 14 and a reduced front portion 15, ortion 14 fitting snugly in the passage 7 an the reduced portion loosely therein so that a circular film of oil shall be discharged from thefront endof the bore or passage and thus mix more readily With the Huid as hereinafter explained. The valve is provided with a handle 16 at its rear end by which it may be screwed forward to cause portion 14| to .partially or wholly nut 18 also mounted on the burner, a suitablepacking 19 being clamped between said dished surfaces to make the joint absolutely V liquid tight.

-20 indicates the burner cap screwed 'uponi the front end of .the body portion of the burner, and provided with a burner orifice 21 in its front end, said cap fitting snugly on the enlargement 5 so that the latter shall constitute a skeleton partition between the front portion of the cap passage-which portion constitutes the mixlng chamber-'and the rear portion of said cap passage, said last- `named portion communicating with and forming a continuation of fluid passage 10. Rearward of the cap, `a-nut 22 is mounted on the body portion andis dished in lts front bythe rear end of the ca this packing like packing 19 and the packlngof the packing nut, belng of mineral wool or other non-com- With the parts arranged as shown in Fig. 1, the oil may pass through passage 7 and the fluid through assage 10, sald fluld being under considera le pressure in order that by passing through the inclined nicks or slits it shall be caused to'whirl s irally in the mixingl chamber and thus e ect practically instantaneous vaporization` of the oil as the latter enters such chamber, the combustible mixture thus formed being discharged with side to receive a packing 23 clamped therein considerable force through the orifice 21 where it is ignited by a li hted match or taper and burns fiercely an with but little nolse. To reduce the flame the valve is moved forward to partially close passage 12, and if itis desired to cut H the oil supply j entirely, the valve is screwed forward a suffiuntil the temperature of the oven or furnace falls sufliciently to eliminate all danger of injury to the burner. The attendant then screws the valve forward until it projects through the burner orifice to prevent the latter becoming clogged with as haltum or other residual propertiesof the oi For use in Lovens for baking crackers, cakes and like art1cles, it is preferred to provide the burner with a long narrow burner orifice arranged horizontally so as to produce a horizontal fan-like flame.

In Figs. 6 and 7, the burner cap'is provided with a slot 24, and with longitudinal guide lugs 25, above and below the slot. 26 indicates a slide plate mounted between said guide lugs and provided. with a T-shaped notch in its rear edge and extending into saidnotch is the front end of'a valve rod 158L corresponding in function and general construction to the valve of Fig. 1,. the front end of said rod terminating in a head 28 journaled in the stem portion of the T-shaped slot 27, so that when said'rod is turned to move forward or rearward, it shall 'cause the slide plate 26 to move in the same direction, it belng understood that said valve rod can be moved forward. sufficiently to project the slide plate through the slot 24 and thus prevent any possibility of the latter becoming clo ged up, as explained with reference to or1 ce 21. l

From the above description it will be apparent that I have produced a burner possessin the features of advantage enumerated as deslrable in the statement of the object of the invention and I wish it to be understood that I do not desire to b'e restricted to the exact details of construction shown and de. scribed as various changes in the form"7 proportion, detail construction and arrangement of the parts may be made without departing from the principle of construction involved.

Having thus described the-invention what I claim as new and desire to secure by Letters Patent, isz-f 1. A burner comprising a body portion provided with an oil assage, and a reduced extension through w 'ch said passage continues and provided also with a uid passage exterior .to said extension and with tubular bosses communicatin respectively with the oil passage and the uid passage a packing nut on the rear end of the body portion, an enlargement at the front end of the reduced extension provided with nicks or slits, a ca fitting ,around said reduced extension an snugly engaging the enlargement thereof and screwed at its -rear end to the body portion of the burner and provided at its front end with a jet orifice, and a valve comprising a threaded portion extending through said packing nut and bearing a threaded relation with sald oil passage, a non-threaded portion having a liquid-tight joint with the oil passage and adapted to cut 0E communication between the same and the tubular-boss passage communicating therewith, and a reduced extension fitting loosely in the [forward portion of said oil passa e and adapted to project through the jet ori ce and cut olf the supply of fluid therethrou h. l

2. A burner comprising a ody having a reduced extension and provided with oil and fluid passages, the oil passagev e'xtendjaigv through the extension and the fluid passage extending outside the extension, a cap s'e-` cured to the body and inclosing the extension and provided with a jet orifice in alinement with said extension, a skeleton partition within the cap around the end of the extension, and a valve arranged in and movable through the extension to successively cut off the flow of oil through the extension and to close the said jet orifice.

In testimony whereof I affix my signature; inthe presence of two witnesses.
